+====================================================+==================================================================================================================================================================+
| v11.10 | This migration adds a new composite index, ``idx_propertyvalues_groupid_updateat_id``, on the ``PropertyValues`` table covering the columns ``GroupID``, |
| | ``UpdateAt``, and ``ID``. The ``PropertyValues`` table is part of the Properties/Custom Attributes feature introduced in recent Mattermost versions. This index |
| | improves query performance for lookups and range scans that filter or sort by ``GroupID`` and ``UpdateAt``, which are common access patterns for this feature. |
| | The index is created using ``CONCURRENTLY``, so the build process does not block concurrent reads or writes against the ``PropertyValues`` table. The migrations |
| | are fully backwards-compatible and no database downtime is expected for this upgrade. The SQL queries included are: |
| | |
| | .. code-block:: sql |
| | |
| | -- morph:nontransactional |
| | CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_propertyvalues_groupid_updateat_id |
| | ON PropertyValues(GroupID, UpdateAt, ID); |
| | |
| | .. code-block:: sql |
| | |
| | -- morph:nontransactional |
| | DROP INDEX CONCURRENTLY IF EXISTS idx_propertyvalues_groupid_updateat_id; |
| +------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| | This migration adds a new nullable ``lastnotifiedat`` column (``bigint``) to the ``useraccesstokens`` table. The column is intended to track the last time a |
| | notification was sent for a given user access token, enabling improved token-related notification logic. Because the column is nullable with no default value, |
| | PostgreSQL performs a catalog-only operation — no table rewrite occurs — and the lock is held for only a few milliseconds. Previous versions of Mattermost will |
| | simply ignore the new column, ensuring seamless compatibility across a rolling upgrade. The migrations are fully backwards-compatible and no database downtime |
| | is expected for this upgrade. The SQL queries included are: |
| | |
| | .. code-block:: sql |
| | |
| | -- Up migration |
| | ALTER TABLE useraccesstokens ADD COLUMN IF NOT EXISTS lastnotifiedat bigint; |
| | |
| | -- Down migration |

Customers will have 9 months to plan, test, and upgrade their PostgreSQL version before the new requirement takes effect. This policy aims to provide clarity and transparency so you can align database upgrades with the Mattermost release schedule.
